Wine may help curb tooth
cavities, shows an Italian studies. Even with the alcohol
removed, red and white wine may fight bacteria that cause
cavities, reports CBS News. But it's too soon to conclude
since the tests have been done in a test tube.
The researchers, who work at Italy's University of Pavia,
included Gabriella Gazzani, Ph.D.
First, they went to a local grocery store,
where they bought some red and some white wine.* Back at
their lab, the researchers stripped the wine of alcohol.
They did that to prevent ethanol from interfering with their
Next, the researchers marinated cavity-causing
streptococcal bacteria in the wines. Both types of wine
countered those bacteria and other streptococcal bacteria
that cause some cases of throat infection.
Red wine might have had more antibacterial
properties than white wine, but that wasn't certain, Gazzani's
The researchers also isolated acids found
in red wine and white wine and tested those acids against
the same bacteria, called S. mutans and S. pyogenes.
The isolated acids were more effective
against the bacteria than the wines. The researchers reason
that while wine fights S.mutans and S. pyogenes.,
Wine also contains compounds that dilute those benefits,
to some extent.
The study is quite preliminary. It appears
online in the Journal of Agricultural and Food Chemistry.
